| Numerical values of the path integrals for low and very low frequencies. (Volume NBS Technical Note 319) - Berry, L. A. (Leslie A.); Chrisman, Mary E.
Numerical values of the path integrals for the first five hops are given as a function of distance from 1000 km to 8000 km, for frequencies of 10, 20, 30, 60, 100, 150, and 200 kHz., for sea paths, and for land paths with conductivities of 0 * .01 and 0.0
